Every metal becomes a factor of some planet in Sanatan Dharma and has auspicious and unfavorable consequences in life. Copper is stated to be deserving of devotion in Hinduism. Many people use copper coins (Tambe Ka Sikka) to improve their luck. According to astrology, a copper coin can help to mitigate the impacts of negative planets in the horoscope.

• Many Rituals and Yagnas involve tamba sikka.
• Throwing a copper coin into the river is also thought to erase the planetary impediment.
• It is used in the Greh Pravesh Pooja ritual.
